Neutron Diagnostics of a Substance in the Liquid State

02.10.2018 Vadim

A classification of substance in the liquid state is presented. The methods of neutron diagnostics of the liquid state of substance are considered. The methods of neutron diagnostics are based on the study of the full scattering cross section or the total neutron absorption cross section, as well as on the study of differential and double differential cross sections of neutron scattering. It is shown that neutron diagnostics allows to determine the structure, equilibrium and kinetic properties of liquids and liquid systems. Moreover, in contrast to optical or X-ray diagnostics,…

Physical Modeling of Atmospherical Emergency Releases (Measurement of Lagrangian Turbulence Characteristics)

02.10.2018 Vadim

Diffusion experiment results simulating emergency releases in atmosphere surface and boundary layers are addressed. Interpretation of measurements was carried out as based on Lagrangian similarity hypothesis and theory of homogeneous turbulence. Universal empirical constants were obtained. A model is described for calculating diffusion parameters and admixture concentration field from diverse sources in near-surface atmosphere layer. The estimates are compared to independent measurements of admixture concentration. Simultaneous measurements of Eulerian and Lagrangian turbulence characteristics in atmosphere boundary layer allowed assessing turbulence scales in Lagragian variables for conditions close to neutral stratification.…

The Safety Problems of Nuclear Power. The Lessons of Chernobyl

02.10.2018 Vadim

The problems of nuclear safety as a complex system are considered. It is shown that the reliability and safety of a nuclear power plant determined does not only reliable structures of the main equipments and qualification of the staff, but especially strict compliance with the priorities of the Security over the economic, political and other factors. Failure to observe this principle has become a real cause of several accidents in the global nuclear power industry, accompanied by the release of radionuclides into the environment. The lessons of Chernobyl remain unlearned,…

Thermodynamics of Melts

02.10.2018 Vadim

Thermodynamic properties of one-component and multicomponent systems, equilibrium in a homogeneous multicomponent system and equilibrium conditions in a heterogeneous system, the Gibbs’ phase rule and its application in status diagrams, are considered. Nonideally diluted and regular solutions are analyzed; basic thermodynamic functions are obtained for binary regular solutions. The main provisions of quasi-chemical theory of solutions and its application in regular solutions are given. Quasi-chemical interpretation of short-range order is seen. Component solubility in different phases is studied. Based on status diagrams, vibrational entropy of dissolved impurity was estimated. The…
